Hi Gilbertio,

ad 1) the originator has exclusive access to write to the target device (e.g. in case of outputs or similar) and listens to certain inputs (reading values) ad 2) the originator asks only to listen to a the targets inputs (reading values) ad 3) as 2), but needs either a 1) or 2) connection to exist. If no ExO or InO connection exist, the connection will not be created. Also if the last ExO/InO is closed a LiO connection will be terminated.
